# The header_matchers plugin adds hash matchers for matching on less-common
# HTTP headers.
#
# plugin :header_matchers
#
# It adds a +:header+ matcher for matching on arbitrary headers, which matches
# if the header is present:
#
# route do |r|
# r.on :header=>'X-App-Token' do
# end
# end
#
# It adds a +:host+ matcher for matching by the host of the request:
#
# route do |r|
# r.on :host=>'foo.example.com' do
# end
# end
#
# It adds an +:accept+ matcher for matching based on the Accept header:
#
# route do |r|
# r.on :accept=>'text/csv' do
# end
# end
#
# Note that the accept matcher is very simple and cannot handle wildcards,
# priorities, or anything but a simple comma separated list of mime types.
